This has honestly been a very fun way to spend the day. I'm gonna probably keep all the frames in seperate sheets and do them individually so I just reassemble them and/or change the coloring depending on the direction she's facing.
Okyuu seems to be able to have pretty much any number of tentacles that she wants but I'm gonna probably go with six both for practical reasons and because her 'legs' are already leg-tentacle hybrid limbs in the first place so this way would give her eight.

The Original Luka actually does, which is because of his desire to act the way he 'thinks' a Hero is supposed to act. So because it's stereotypical for the Hero to be dense he intentionally behaves that way until he eventually realizes why it's not a good idea.

I don't think Singularity Luka has that excuse since he had such a different upbringing and the idea of a hero isn't as important to him as it was to the original one so he could very well just be dense. I do think he's not as dense as he makes himself out to be still, though, but he's denser than the original at least.
